Measurement of B0d - B0d-bar mixing rate from the time evolution of dilepton events at the Upsilon(4S)
K. Abe
We report a determination of the B0d - B0d-bar mixing parameter Delta-m_d based on the time evolution of dilepton yields in Upsilon(4S) decays. The measurement is based on a 5.9 /f…
First Measurement of the Branching Fraction of the Decay psi(2S) --> tau tau
J. Z. Bai
The branching fraction of the psi(2S) decay into tau pair has been measured for the first time using the BES detector at the Beijing Electron-Positron Collider. The result is $B_{τ…
The Electronics and Data Acquisition Systems of a CsI(Tl) Scintillating Crystal Detector for Low Energy Neutrino Experiment
W. P. Lai, TEXONO Collaboration
A 500 kg CsI(Tl) scintillating crystal detector is under construction for the studies of low-energy neutrino physics. The requirements, design, realization and the performance of t…
A Measurement of the Mass and Full-Width of the Meson
J. Z. Bai
In a sample of 7.8 million decays collected in the Beijing Spectrometer, the process J/ is observed for five different decay channels: , $π^+π^-…
A CsI(Tl) Scintillating Crystal Detector for the Studies of Low Energy Neutrino Interactions
TEXONO Collaboration
Scintillating crystal detector may offer some potential advantages in the low-energy, low-background experiments. A 500 kg CsI(Tl) detector to be placed near the core of Nuclear Po…
